I suspect the main reason 3D games rarely simulate water, fire and smoke is the complexity in making them GAMEPLAY RELEVANT. That dragon example looks nice and all but what would you use that for? You can very easily create a flame thrower (or a fire breathing dragon) for your game right now, the flames on which don't look nearly as good of course, and have it set things ablaze. Noone's stopping devs from implementing the gameplay side of things right now. Collision physics would be a lot leaner for gameplay purposes than they have to be to get that volumetric simulation.
Reminder that nOvidia physX are and will always be a graphics gimmick with zero benefit to gameplay. Physics should be about interaction, not about looks. nOvidia doesn't give a fuck about gameplay, they want the screenshotfag audience.
